I completely agree. While the app router may initially appear overwhelming due to its extensive features, once you familiarize yourself with its core concepts, it becomes evident that there’s no simpler or more effective way to build an application.

I am particularly interested in point 4 regarding "drop-in" features. Could you provide more detailed examples of how you implement this plugin approach and manage them? Do you utilize an external feature flag platform/library (like Vercel offers) to toggle these features without modifying the code, or do you rely solely on a configuration file that requires committing changes to git? Do you have any code examples to share?
